Tatiana [17]

Answer: 103/15

Step-by-step explanation:

We can simplify the right-hand side to be 2 \left(\frac{1}{3}+6 \right)=2 \left(\frac{19}{3} \right)=\frac{38}{3}.

This means we need to solve:

\frac{1}{2}(5x-9)=\frac{38}{3}\\5x-9=\frac{76}{3}\\5x=\frac{103}{3}\\x=\boxed{\frac{103}{15}}

Chris wants to triple 63.374. He says it must end in 9. Is he correct? Explain your answer.
alukav5142 [94]
He is wrong.  we are only looking at the last number which is 4
if we tripple 4 or 4*3 we get 12 which ends in 2, not 9

Process control is nothing more or less than monitoring quality as the work is being performed. Perhaps the most widely adopted
ella [17]

Answer:

a. Grand Mean = 2.799

b. Standard Deviation = 0.01387

c. Standard Error = 0.0016

d. The range with a Z score of 3 = (2.75739, 2.84061)

Step-by-step explanation:

a. Grand mean :

Given that

Sum of 80 values = 223.91

Total observation = 80

Grand mean = 223.91/80 = 2.799

b. With the excel command "STDEV[range of cells]", we get the standard deviation as = 0.01387

c. Standard error =  Standard deviation / root of n

= 0.01387/\sqrt{80}\\ = 0.0016

d. The range with a Z score of 3 :

lower limit = mean - (3 * SD) = 2.799 - (0.04161) = 2.75739

upper limit = mean + (3 * SD) = 2.799 + (0.04161) = 2.84061
